Application filed December 13, 1915'. Seria1-No.'66,525.

To all whom it may concern Beiit knowni that I, GRAYAI. Monmss a whichthe following is a specification;-

This invention relates particularly' to a tlrying room intended forbaking enamel: on

metallic surfaces, as, for-instance, automo bile bodies or the like.

The objects of the invention are toso arrange the. heating :and a incirculating devices as toi'maintain a substantially;-uniform de .ggrce Yof heat and dryness throughout l the drying chamber; and to providefor-the ready introduction 0t automobile bodies or the like into thedrying chamber by the :proi vision oi' a zturnetable fioor so arrangedas to be exposed one-half within the drying cham ber, and the other halfoutside: of the chamber, toithe end. that the stacking'up of onechargeof enamel; ware :or the like; may proceed concurrently within the dryingor haloing of) another 1 charge, thereby expeditingthe drying operationand conserving theheat within the drying room to the greatest possibleextent.

The invention, furthermore, relates :to-the- ,closurefor the drying roomwhich is m0unted-upon and rotated with :theturn table in.- sucha manneras to open and close the-drying roo1n=by-the act of rotating'theturntable, so that the charge of enamel ware may be introduced into, thedrying or baking room simultaneously with the removal of the precedingcliargeaand a-closure effected so quickly as to prevcntthe, escape ofheat from the drying room.

In the drawings: Figure 1 is a front elevation ofthedryingroom showingthe r0- tating door ior closing wall removed toex posethe interior; Fig.2'is a sectiOnalplan view; of the same, showing the rotating doorQinplace; Fig. 3 is-a top or plan view Show ing the ar 'angement of thecirculating and ventilatingzpipes; andFig. 4 is a detail of" the same insideelevationr Theid'ryi-ng or baking room 5, as shown,

is of semi-polygonal shape; closely proximat ing the outline of theturntable- 0 which forms the floor of thedrying'chamber; The

drying chamberis formcd by-a vertical wall 7 of the shape 1nenti0ned,which wall is--in'-- iiclosed with double exterior walls S -ex-tend-Specification of Letters Patent'.

ing inangula'r relation to one another, and each terminatingcin a shortinwardly ex-. tending double walli 9 which terminates in vertical,alinement with the periphery of the i turn table giving to the exteriorof the structure theshape, in plan,-of a square hav- 7 ing one of itscorners cut away or truncated. The inner terminal edges of the walls 9are in alinement with the greatest diameter of thetu'rn-table, so thathalf of the latter projocts exteriorly of the drying or baking chamber5, from which the projecting portion issepar-ated by a double-\ 'alledrotating doorvl0 built upon and vertically extending from 1 theturn-table and adapted to rotate therewith." The ends 11 of the rotatingdoorare laterally spread or-extended to furnish bearingisurfacescontacting with or inveryclose relaitionto the inner edges of thewalls9;sothat when the turn-tableis moved to the position shownin Fig. 2, therotating door will. serve i to -close the drying -or baking-- chamber,thereby preventing-the escape of heat units "therefrom, and alsopreventing the ingress" of moisture or dust. The exteriorwalls are inspaced relation with respect-to the polygonal wallof the drying orbaking chamber,'- and this aifords a central hcatingchamber 12 andsupplemental heating chambers 13 in communicationwiththecentral heatingchambers, the arrangement beingone which aiiords, in efle'ctyacontinuouslieati-ng chamber-around the entire innor surface of thedrying or baking chamberr The heating chambers have located thereinheatin'g coils 14: or the like, adapted anclpi'oje'ctthrough theexterior walls near theflo'or level, which pipes-serve to create acirculation orsuction of air from the drying or baking chamber;underneath the lower edge of the polygonal wall. These eduction pipes 11 and 15 extend to a point above the level of the ceiling or top 17 ofthe structure, at which point their ends 18 and 19 are inturned andconverged together in a drum 20, which communicates with a fan or blower21 having a discharge pipe 22, which is down turned through the ceilingnear the center of the drying or baking room and serves to discharge theeducted air back into the drying or baking room, and to maintain thecirculation therethrough, and to induce additional circulation of heatedair directly over the upper edge of the inner polygonal wall of thedrying or baking chamber, thereby serving to induce currents of airdirectly from the coils, and into the top of the drying or baking room.

In order to provide for the eduction of foul or saturated air from thedrying or baking room, a plurality of ventilating pipes 23 and 24 areprovided which extend upwardly through the ceiling of the structure, andcommunicate respectively with the drying room and the heating chamber,and these pipes 23 and 24:, at their upper ends, communicate with theangles of a triangular header pipe 25, which at points intermediate itsangles communicates with inwardly extending leads of pipe 26 whichconverge together and merge into a single ventilating flue 27 adapted toeduct the foul or saturated air to a suitable point of discharge.Suitable provision may also be made for the introduction of fresh air,if desired, but, of course, the opening and closing of the rotatingdoor, due to the movements of the turn table, will admit a considerablevolume of fresh air, and additional air will ordinarily not be requiredexcept in special circumstances.

In use, the automobile bodies, or other enamel ware or articles, desiredto be dried, will be stacked up on the exposed portion of theturn-table, and after the stack is complete, the turntable will berotated to turn the previously exposed section back into the drying orbaking chamber, after which the fan or blower can be started and thedrying proceeded with. During the interval required for drying, a secondcharge of enamel ware or the like can be stacked up, so that, by thetime the first charge has been dried or baked, a succeeding charge canbe immediately turned back into position. This not only greatlyexpedites the operations involved, but also tends to conserve the heatunits and obviates the necessity for the workmen entering into thehighly heated baking or drying chamber, which is not only unpleasant butis also prejudicial to health in view of the presence in greater or lessquantity of the fumes from the varnish or enamel. The arrangement is onewhich permits the articles to be stacked up carefully, and under mostfavorable conditions, is

economical of floor space and more satisfactory from every standpointthan would be the case if the turn-table were not employed. Theemployment of a rotating door or closing wall mounted upon theturn-table itself insures the immediate closing of the door as thearticles are turned back in place, thereby conserving the heat units andpreventing the stirring up of dust and simplifying the operationsinvolved to the utmost.
